What This Code Means

Severe chemical burns affecting 90% or more of the body with 80-89% of the burns being the most severe third-degree type that destroys all skin layers.

Coding Tips

•This represents extremely severe corrosion with high mortality risk; ensure accurate documentation of burn depth percentages
•Always include seventh character for episode of care and consider multiple codes if different body regions have different burn depths

Clinical Significance

This indicates severe chemical burns affecting 90% or more of the body with the deepest burns covering 80-89% of that area. This represents one of the most catastrophic chemical injuries possible, with near-total full-thickness destruction and extremely high mortality risk requiring immediate intensive burn care.

Documentation Requirements

✓Body surface area documentation (90% or greater)
✓Third-degree burn extent (80-89%)
✓Chemical agent and concentration details
✓Exposure timeline and emergency response
✓Current treatment status and prognosis
✓Anatomical areas with minimal viable tissue
✓Associated organ failure complications
✓Extensive surgical interventions and outcomes
